Question

State the various postulates of Daltons atomic theory of matter??

Answer 1

The postulates of Dalton’s atomic theory are as follows:

All matter is made up of very tiny particles. These particles are called atoms.
An atom cannot be divided further i.e., atoms are indivisible.
Atoms can neither be created nor destroyed in a chemical reaction.
All atoms of an element are identical in all respects, including the mass, chemical properties, etc.
Atoms of different elements have different masses and chemical properties.
Atoms of different elements combine in small whole number ratios to form compounds.
In a given compound, the relative number and types of atoms are constant.

Answer 2

1.All the matter is made up of very small particles called atoms
2.atoms can neither be created nor destroyed
3. All the atoms of a given element are identical in every respect having same physical and chemical properties
4.atoms of different elements differ in every respect I.e, mass, size and chemical properties
5.during chemical combination atoms of different elements combine in small whole numbers to form compounds
